12 Claims.

This invention relates to a device for measuring thread, yarn, cloth andthe like, and to count rotation, and the principal objects thereof areto provide a simplified construction for stop- 6 ping the operation]when a predetermined number of yards have been measured; to provide aconstruction for this purpose which will elimihate the use of gears andwire clutches and also to provide it in a form in which the number ofparts is reduced to a minimum and the use of a wire clutch and othercomplications heretofore thought necessary are avoided.

Other objects and advantages of the invention will appear hereinafter.

Fig. 12 is a view similar to Fig. 8, showing the" parts in a differentposition.

This machine is intended for measuring the amount of thread or yarn Twhich passes around a measuring wheel 10. This measuring wheel is of anordinary character having a V-shaped groove around its circumference inwhich the yarn is usually given several turns, it being understood thatthe yarn comes from another wheel having a groove and that the wheel 10has a definite circumference and in one revolution thereof measures thatlength of yarn, as for example, one-half yard. When this wheelturns onerevolution therefore, one-half a yard of yarnhas'been passed around itand measured.

Fig. 10 is a sectional view on the line 10- -10 I disc can be turned inthat direction only. In

This wheel delivers to another machine, such as a winding machine, whichturns the wheel by drawing the yarn over it.

This wheel 10 is mounted on a shaft 11 on which is a worm 12 located ina circular casing 13 having bearings 14 for this shaft. The casing 13stands vertically on a base 9. In this casing 13 is a central shaft 15on whichis mounted to freely rotate a worm wheel 16 meshing with theworm and having a fine thread. ,Therefore a single rotation of the wheel10 will be trans mitted to the worm wheel 16 and rotate it one threadspace. This wheel 16 has a fiat face at one side rotating against a ring17 fixed to the back of the casing 13 and constituting a flat bearingtherefor. The wheel 16 is upset to form an annular groove 18 on oneside, which in itself has no function, but this upsetting provides anannular projection 19 on the other side.

Within this projection'is located a clutch disc This clutch disc isperforated at the center, so that it will have no bearing on, the shaft15 and provided with a radial-slit 21, so that it can be expanded orcontracted and this slit extends at the other side in the form of a slot22 so that. there is only a thin piece of metal to connect the twohalves of this disc. .The disc is also provided with a radial slot 23 bywhich the disc can be turned. This disc is set in the central circularspace within the annular projection 19. Obviously, if some instrument isinserted in the slot 23 and pushed in one direction, that is, theydirection away fromthe s1it.21, it will expand the clutch disc andprevent its turning in its circular space, but if pushed in thedirection. toward the slit, it will contract the disc and the order forthe disc 20 to engage the annular projecting flange 19, for driving, thedisc 20 has to be initially expanded.

The shaft 15 also carries fixed thereon a scroll wheel 24 which isprovided with a pin 25 entering the slot 23. Therefore the scroll wheelcan be turned, forwardly but not backwardly. This scroll wheel isprovided with a spiral scroll groove, indicated in Fig. 6, on the frontface thereof for cooperation with a scroll roll 26.

On the back of the front plate 28 of the machine, which fits within theopen end of the casing 13, is a fixed plate 29 having a vertical slot 30which constitutes a guide for a. slide 31. This slide has ahorizontalarm 32 projecting at right angles on which a flange on the roll 26 isadapted to rest. This flange is comparatively sharp and runs in thegroove in the scroll wheel 24. The slide is provided with a 50 'tion tothe spring-pressed wedge-shaped stud 42 and that the roll 26 is movedback into en- Also this stud 35 carries a pointer 38.

. hollow stud 35 is mounted on the shaft and is freely rotatable thereonand is centered thereby with respect to the rest of the apparatus. Thepointer 38 is turned by the hand wheel 36 I to the desired point on ascale 55 to set the device to measure the number of yards so indicatedon the scale. This action lifts the slide and arm 32 and therefore theroll 26. The latter will start from the point at which it is set and, aswill be seen later, will move the rest of the distance along the rod 39.

The scroll wheel 24 has at the end of the scroll a fixed stud 40. Whenthe roll 26 is gradually moved out along the scroll and cau ht in theextremity of the groove, which terminates in the stud 40, also grooved,the roll will ride up on this stud. This roll is mounted on a verticalrod 39 carried by a pivoted frame 41, normally held out in position forthe roll to engage the scroll by means of a pointed spring latch 42 asshown in Fig. 12; When the roll 26 is positively forced backwardly bythe stud 40 the back end of this plate 41 will pass over theinclined-surface of the stud 42 and hold the plate'to the position shownin Fig. 8. Then the roller no longer engages the wheel 24 and themeasuring operation is stopped. The'plate 41 has a rigid stop 43 adaptedto engage the plate 28.

The movement of the plate 41 to again set the roll 26 back into thegroove on-the scroll wheel 24 is controlled by a hand lever which can beoperated by a link or cord connected to the winding machine, not shown.This'lever is pivoted by means of a round opening i7 and a stud 48 andhas an opening 19 for receiving an arm 51') on a shaft 51.- This shaftalsohas another arm 52 which has a notch 53 for engaging on both sidesof the edge of the platej ll at a distance from its pivots l4. Thearm'52 is moved by the plate 41 to move the lever 45 and stop thewinding machine when the roll is thrown out of the scroll. This, ofcourse, stops the drawing of the yarn over the wheel 10 and itsrotation. r

It will be seen, therefore, that the downward movement of the arm 45will swing the plate 41 about its pivot in a positive manner incpposigagement with the scroll and the stud 42 will hold it there untilit is disconnected therefrom. by the stud 40. Themachine has to be setafter it has once completed its operation but ordinarily that is all theattention that has to be given .it. Of course, it can be. stopped andrestarted by this handle 15 at any time. When the roll 26 is moved backby the stud, the ma chine is set. at zero byhand. At the top of rod '39there is a spring 49 for providing a slight resistance againstthe roll26 when it gets near the end of the scroll and is, ready to engage thestud 40. y

What has been described so far relates to the operation of themachinefor measuring yarn in even thousands, or in such fractionsthereof as can be gauged accurately on a circular scale 55 by means ofthe pointer 38. By reference to this scale it will be seen that acomplete revolution of the pointer 38 is intended to showthat 20,000yards havebeen passed over the wheel 10 and that each of the divisionson the scale represents 250 yards. It is possible to set the scale thenaccurately at every 250 yards from zero to 20,000 yards. For the purposeof setting it at finer points'a pointer 56 is employed which is rigidlymounted on the central shaft. 15 on which the scroll wheel'2 l is fixed.This pointer is provided with a pin 59 having a knurled handle 58. Inthe face of the instrument between the plate 28 and the cover 60 thereis mounted a circularspring 61 having an'end 62 extending inwardlyradially and the other end not connected to it. This spring expands intothe space between these two plates and can be turned in only onedirection obviously. The projection 62 constitutes a gauge for thepointer 55. When the flexible pointer is pressed back this gauge acts asa stop for original setting, but when released the pointer springsforward and the gauge no longer acts as a stop for it and it passes thegauge at each revolution of the shaft The outside scale is numberedfromzero to 200 and cooperates with the pointer 56 so that after the pointer36 is set, as for example, to the point 17,590'this gauge 62 canbe setfurther as for example, to the position 32 as shown. The setting of thepointer 56 back to zero takes with it the scroll wheel 2&1. So afterhaving been set by the pointer '38 to come back to zero upon the windingof 17,500 yards of yarn as shown, it 'will be set farther over so thatthe stud'll will'be offset from the zero point to allow 32 -2 yards'more to be wound before the stud then the measuring is automaticallystoppedthrough action of the lever 45 on the usual stopping means on thewinder; All that has to be done then is to turn back the pointer 56 andpull the handle 45 and it will be set again to reel off the same amount.I

Before starting the device, the pointer 38 is turned to the properposition and thatv turns the pinion '34 and moves the arm 32 along therod 39 to the'proper point. it is to be remembered that the roll 26 hasa flange so that it never can pass below the arm 32 and this settingwill carry this roll up to the proper position to begin operations, theroll resting on the arm.

Now if the division on the inner scale is to be. divided further thepointer 56 is turned to turn the wheel 24 and bring the pointon thescroll back from zero .a further distance. This does not affect the arm32 but makes it necessary for the scroll wheel to rotate through afurther arc in order to bring the stud 40 up to zero point and depressthe Wheel 26 and therefore turn the plate ll 'rom the position shcwn'inFig. 8. This constitutes the settin'gof the device.

flow in operation the roll 26 is graduallyin case it should stick. I

If the operation is to be repeated with the same yardage no attentionhas to be paid to the pointer 38'but the pointer 56 has to be turnedback again to the same position it was in before and then the arm 45 ispulled down which again pulls the plate 41 over and moves the roll 26vintocontact with thegrooved surface of the Z is nothing to support it soit drops back again, on the arm 32. A spring 49 startsthejroll down.

in'p'osition. in said shaft to be engaged by said plate 24 ready toagain.-

-"Ihe method ,of changing it for a different.

yardageghasalready been explained. It may be mentioned that the pointer56 is flexible and I can be forced down by the handle 58 until the pin59engages behind: the pointer 38 and then that pointer can be movedaround conveniently by the handle 58.

wThesetting of the device is of the simplest possible-character, theoperation is certain and not-dependentupon any springs, the use of geartrains and spring wire clutches are eliminated and the mechanismingeneral is reduced to very simpleterms The cost of, productionnecessarilyiis reduced and also thenumber of-parts that may get out ofrepair is very small.
